Multiband SRR loaded Koch star fractal antenna

The Split ring resonator [SRR] loaded Koch star fractal antenna for multiple Freq band apps is presented. The CPW-Fed ant consists of Circular Split Ring Resonator [CSRR] which is fixed on reverse side of the substrate and iterated Koch star which is stamped on top of the FR4. The Koch fractal SRR antenna with a compacted size of 12 x 14 mm(2) is fabricated and tested. The multiple Freq for antenna measured capitulate with a -10 dB at 1.88/6.54/7.88/12.20/15.08 GHz bands and cover up the Freq spectrum of GSM, WiMAX, IEEE 802.11a (WLAN)/b/g, IEEE 802.16e, ITU, S/C/X/Ku and K band, correspondingly. The extraction method of -ve permeability for the projected circular slit resonator is examined in detail. The antenna projected to have significant recompense, plus low profile, miniaturization capability with good S11 and VSWR is accepting for the functional frequency bands.
